- Geez, I realize I forget to state the version I'm using: 3.1.

- I had been doing all my testing from a cold start-up. But when I go back
now and keep testing over & over, I keep seeing the problem over & over.
But
reading the re****t you linked to, it *does* seem to me like it describes
my
problem, and that it could happen any time, not just soon after starting a
listen.

If this gets fixed in a near-term release I'm good. Right now, I can
kludge
around it with a double-query of the modified table--because right now the
usage patterns are such that I don't think this will ever skip an update.
(Longer-running updates, or a heavier load, and I might have a bigger
problem.)

Four years of using PostegreSQL, and finally there's a bug that actually
affects the correct operation of my software. Not too shabby ;-)
